Description

A kind of Herbicidal combinations and its application method and purposes

Technical field

The present invention relates to pesticide field more particularly to a kind of Herbicidal combinations and its application methods and purposes.

Background technique

Soybean is originating in China, there is cultivation all over China, most famous with northeast, also cultivates extensively in all over the world.2018 Year, 7,780,000 hectares of Chinese soybean sown area, be the important cereal crops in China.Anti- dicamba genetically engineered soybean is by the U.S. What the trans-corporations such as Monsanto Company, Syngenta Co., Ltd, Switzerland and The Dow Agrosciences, LLC. released in the beginning of this century has anti-remove The genetically engineered soybean of careless agent dicamba performance.Because it can directly spread fertilizer over the fields herbicide dicamba, injury will not be generated to soybean, and it is big The labour of amplitude reduction farmer and production cost.

Dicamba category benzoic acids herbicide has auxins weeding after the seedling of selectivity and uptake and translocation effect Agent, the lasting period is long, is mainly used for the weed control of cereal, corn, sorghum, sugarcane, pasture and non-field-crop etc..To 1 year Raw and perennial broadleaf weed has significant preventive effect.Dicamba be used for it is spraying after seedling, medicament can quickly by the leaf of weeds, stem, Root absorbs, and is conducted up and down by bast, and focus mostly on the position vigorous in separate living tissue and metabolic activity, and plant is hindered to swash The normal activity of element, to make its death.The cracking progress metabolic breakdown of energy is allowed to fail after gramineae plant absorbs medicament, therefore Show stronger drug resistance.Safer to gramineous crops such as wheat, corn, millet, rice, dicamba is in the soil through micro- It disappears after biological very fast decomposition, general 24 hours broadleaf weeds both will appear deformity curling symptom, death in 15~20 days after.

Cloransulammethyl is sulfonamides selective herbicide, and sterling appearance is white solid.It is sprayed for Soybean Field cauline leaf Mist prevents and kill off broadleaf weeds.Show through toxicity measurement and field control effectiveness test to early soybean field broadleaf weeds dayflower, red Knotweed, artemisiifolia have preferable control efficiency, have stronger inhibiting effect to Chinese Ixeris, sowthistle.It is absorbed through grass cutting blade, root, accumulation In growing point, inhibits acetolactate synthestase (Acetyl lactate synthetase, ALS), influences the synthesis of protein, Weeds are made to stop growing and dead.

Pesticidal products during use, wave by secondary on blade of drift and active constituent for being easy to happen droplet Hair.Drift refers to that droplet is atomized device and trickles down to during reaching crop leaf, since the droplet of pesticide is meticulous, too light and side To shifting, fail to fall in target crop.Secondary volatilization refer to pesticide droplet after falling in crop leaf surface, activity Ingredient, which is not absorbed by weeds, to be just volatized into air.These problems lead to pesticide in use, the utilization of active constituent Rate is low, and peasant household has to improve usage amount and in a disguised form increase drug cost.Meanwhile drifting about and being volatized into the active constituent of air It is easy to generate phytotoxicity to the crop on periphery, causes unnecessary loss.

CN106719731A discloses a kind of Soybean Field postemergence weed control composition of chloro-ester sulphur grass amine, the Herbicidal combination The active constituent of object is fomesafen, cloransulammethyl and clethodim, the fomesafen, cloransulammethyl and clethodim Weight ratio be 0.1-80:0.1-80:0.1-80.Herbicidal combinations of the present invention are relative to exclusive use cloransulammethyl The obvious Zeng Qiang of herbicidal effect, but there are still dosage is administered, big, the problem of quick-acting difference is applied when its formulation rate is 80mL/ mus 10 days strain preventive effects are only 75.6% after medicine.

CN1398266A discloses a kind of Herbicidal combinations containing cloransulammethyl and imazamox, active constituent For cloransulammethyl and imazamox, the weight ratio of the cloransulammethyl and imazamox is 4:0.2-20, chlorine ester sulphur The weight of careless amine and imazamox accounts for the 20-60% of Herbicidal combinations total weight, and the Herbicidal combinations are relative to simple chlorine The herbicidal performance of ester sulphur grass amine is obviously improved, but still there is cooperative synergism effects between cloransulammethyl and imazamox not Obviously, application dosage is big, 75g/ hectares of the content > of active constituent in single administration amount, lasting period short problem after application.

CN104351216A disclose it is a kind of include cloransulammethyl Yu clethodim two kinds of active components Herbicidal mixture The preparation method and application of agent and this kind of mixed herbicide.The matter of cloransulammethyl and clethodim in this kind of mixed herbicide Amount is than being 5-60:1-25, and cloransulammethyl and clethodim the gross mass mass percent in herbicide are 6-75%, this scheme is deposited The lasting period short problem after application, strain preventive effect when being administered 20 days is 93%, and 40 days strain preventive effects are reduced to after being administered 83%.

Although above scheme provides the composition of some Herbicidal combinations, but still that there is formulation rates is big, and quick-acting is poor And lasting period short problem after application, therefore develop that a kind of formulation rate is small, quick-acting is good, lasting period long Herbicidal combination after application Object is still of great significance.
